Step 4

Place tuna, corn, mayonnaise and chives in a medium bowl. Stir to combine. Starting from 1 long side, cut nori sheets into 6 even strips.

Fill a small bowl with cold water. Dip fingers in water and shake off excess. Using 1 tablespoon of rice mixture at a time, shape rice into a rectangle with slightly rounded edges. Wrap 1 strip of nori around rice to create a border, using a little water to seal nori, trimming excess nori.
